An anonymous reader writes: Last night I received a call from a company posing as a job recruiter and asked about my background that they found online. They proceeded to ask me a series of specific questions in a "How does one do this?" format that related to my years of experience in the area. Thinking that this might be a potential job opportunity, I felt obligated to answer all their questions, but realized after a while that they were not really looking for a candidate but instead were unscrupulously scouring for information in gathering estimates and software resources for a project. I was a victim of knowledge rape. Unpaid for my services, I felt that I should contact an agent or a lawyer, instead I chose slashdot.
